Title: Ensuring date integrity in multiprocessor or pipelined processor system
Inventor: SITES RICHARD L
IPC: G06F15/16
Filed: 1991-06-28
Abstract: ENSURING DATA INTEGRITY IN MULTIPROCESSOR      OR PIPELINED PROCESSOR SYSTEM                ABSTRACT OF THE DISCLOSURE    A high-performance CPU of the RISC (reduced instruction set) type employs a standardized, fixed instruction size, and permits only simplified memory access data width and addressing modes.  The instruction set is limited to register-to-register operations and register load/store operations.  Byte manipulation instructions, included to permit use of previously-established data structures, include the facility for doing in-register byte extract, insert and masking, along with non-aligned load and store instructions.  The provision of load/locked and store/conditional instructions permits the implementation of atomic byte writes.  By providing a conditional move instruction, many short branches can be eliminated altogether.  A conditional move instruction tests a register and moves a second register to a third if the condition is met; this function can be substituted for short branches and thus maintain the sequentiality of the instruction stream. Performance can be speeded up by predicting the target of a branch and prefetching the new instruction based upon this prediction; a branch prediction rule is followed that requires all forward branches to be predicted not-taken and all backward branches (as is common for loops) to be predicted as taken.  Another performance improvement makes use of unused bits in the standard-sized instruction to provide a hint of the expected target address for jump and jump to subroutine instructions or the like.  The target can thus be prefetched before the actual address has been calculated and placed in a register.  In addition, the unused displacement part of the jump instruction can contain a field to define the actual type of jump, i.e., jump, jump to subroutine, return from subroutine, and thus place a predicted target address in a stack to allow prefetching before the instruction has been executed.  The processor can employ a variable memory page size, so that the entries in a translation buffer for implementing virtual addressing can be optimally used.  A granularity hint is added to the page table entry to define the page size for this entry.  An additional feature is the addition of a prefetch instruction which serves to move a block of data to a faster-access cache in the memory hierarchy before the data block is to be used.

Title: Optical imaging system for neurosurgery
Inventor: MACVICAR BRIAN A
IPC: G16H20/40
Filed: 1991-08-08
Abstract: ABSTRACT OF THE DISCLOSURE           In accordance with the present invention, a method and apparatus are disclosed for real time imaging of functional activity in cortical areas of a mammalian brain using intrinsic signals.  The present invention enables dynamic, on-line imaging of, for example, a human brain during neurosurgery to permit more accurate identification of dysfunctional cortical areas.  Cortical areas are identified on the basis of stimulus evoked changes which occur in the optical properties of the brain so that real time localization of seizure (e.g., epileptic seizure) foci and functional mapping can be observed during neurosurgery. Areas of pathological tissue such as epileptic foci and tumors can thus be identified and removed during neurosurgery without damaging important functional areas in the cortex near the tissue.
